1 mole of a gas occupies volume 1.00 x 10^-2 m³ in a gas cylinder whose pressure is equal to 2.50 x 10^5 Pa.The temperature of cylinder is:
Correct answer: B. 300K
- A. 227K
- B. 300K
- C. 370K
- D. 390K
Explanation
Rearranging the ideal gas law gives T = PV/nR = (2.50 x 10^5 x 1.00 x 10^-2)/(1 x 8.314) = 2500/8.314 = 300 K.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
